SELVAG-E-LOOP RETAINER.

Application filed November 12, 1923. Serial No. 674,337.-

To all whom it may concern.

Be it known that I, JAMES A. HEnAUL'r, a citizen of the United States, residing at Easthampton, in the county of Hampshire and State of Massachusetts, have invented new and useful Improvements in Selvage Loop Retainers, of which the following is a specification.

This invention relates to improvements in looms and-has for an object the provision of a selvage loop retainer which may be attached to the loom to form a selvage on cotton fabrics, heavy duck, leno, screen cloth and other woven material, in such a manner as to prevent the filling from pulling tight in the selvage and causing saw teeth or fillin cuts therein.

Another object of? the invention is the provision of a selvage loop retainer which is simple in construction, eflicient in operation and may be easily attached to a loom. With the above and other objects in View, the invention further includes the follow ing novel features and detailsof construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

- In the drawings J Figure 1 is'a plan view showing a portion of a loom with the invention applied.

Figure 2 is a side view of the same.

Figure 3 is a section on the line 3-3 of Figure 1.

Figure 4 is a detail perspective view of the temple carried shaft bearing late. f

v Figure 5 is a similar view 0 the lay carried slide plate.

As the present invention relates only to a particular feature in the construction and operation of the loom, it is sufiicient to illustrate and describe only, those parts of. the loom directly concerned with a preferred embodiment of the invention. A familiar type of temple 10, a ortion of the lay 11,

and the weft threa s 12 and the warp threads 13 are shown in their usual relation. Secured to the temple by the bolts'14 is a temple shaft bearing plate 15 which carries spaced arms 16 provided with openings 1 17 for the accommodation of a rock shaft Secured to the temple as indicated at 14 is a temple heel plate 15, the said plate tudinal movement.

carrying spaced arms 16 which are provided with openings 17 for the accommodation of a rock shaft 18.

Rigidly and adjustably secured upon the shaft 18 is an arm 19, while pivotally scoured to the outer end of this arm is loop retaining finger 20, the inner end of which is provided with a hook-shaped portion 21 for engagement through an opening provided in the outer end of the arm 19.

I The finger 20 extends through a slot 22 provided in the temple cap 23 of the loom and is guided backward and forward over the temple burr spindles 24. There are usually two long and two short burrs arranged. within the temple, but in the case of the present invention the long ones are removed and four short burrs 25 are substituted and the finger 20 engages the ends of theseburrs so as to resist any tendencyfor lateral movement. This-finger 20 is preferablyv guided in its sliding movement in the required path by its connection at its forward end with the arm 19 and by resting upon the rear temple burr spindle- 24. The free end of the finger 20 is movable over the weft threads 12 at the fell in a downwardliy inclined position and is yieldingly force in this direction by means of a spring 26 which has one end engaged with the arm 19 and its opposite end engaged with one of the bearing arms 16. Movement of the loop retaining finger in this direction is limited by a stop finger 27 which is adjustably secured to the shaft 18 and engages one of the arms 16.

Adjustably secured upon the outer end of the shaft 18 as shown at 28, is one end of a'cam arm 29, this arm and the stop finger 27 acting to hold the shaft 18 against longi- The free end of the cam arm 29 is located in the path of the cam 30 which iscarried at one end of a plate 31, the latter being adjustably mounted uponthe lay 11.

In the o eration of the invention, after the shuttle as passed the edge of the fabric, as the lay goes back, the loop retaining finger 20 moves rearward over the weft thread, the said finger inclining rearwardly and downwardly. The shuttle in its return movement loops the weft thread over the end of the finger 20, any tendency of the loop to pull inward toward the edge of the fabric being resisted by the said finger. When the lay moves forward to beat in the thread, the cam 30 engages the cam arm 29 which rocks the shaft 18 and moves the loo retaining finger 20 against the action 0 the, s ring 26 and out of the loop of' the weft tliread just formed. It is of course understood that the mechanism is duplicated upon the opposite side of the loom.

It will be noted that the loop retaining finger is a substantially straight piece of wire having a downwardly curved rear end. This finger slides substantially parallel with the edge of the cloth and moves in a path above the cloth. When this finger is projected rearwardly it. passes over the weft beaten in at the fell due to its downwardly curved rear end, its support upon the rear burr spindle and its connection with the swinging arm 19. \Vhen the lay beats up the finger is retracted so as to carry its rear end forwardly of the fell and this is effected in the particular construction illustrated by the eo-operation of the cam 30 and the cam arm 29. The spring 26 acts normally to project the finger rearwardly past and inclining downwardly over the fell. Consequently when the pick of filling or weft is taken toward the side at which the temple is located. and this pick is beaten in the finger is carried forwardly of the fell. As the lay retracts or moves back the finger is immediately projected rearwardly down over the weft and as the pick toward the opposite side takes place the weft is looped over and around the finger. The finger is then withdrawn from this loop on the succeeding beat up of the lay.

The invention is susceptible of various changes in its form, proportions and minor details of construction and the right is herein reserved to make such changes as properly fall within the scope of the appended claims.

Having described the invention what is claimed is v 1. A loom comprising a temple, a lay movable toward and from the temple, :1 selvage loop retaining finger mounted in the temple to slide substantially parallel with and above the edge of the cloth adjacent the fell, means acting normally to project the finger rearwardly past and inclining downwardly over the fell, and means acting simultaneously with the beat-up of the lay to retract the finger forwardlyv of the fell whereby, after the pick of weft toward the side at which the tem le is located is beaten in and the lay moves ack the finger is projected over the weft and the next pick toward the opposite side 100 s the weftover and around the finger, which is then withdrawn therefrom on' the succeeding beat-up of the lay.

2. A loom comprising 'a. temple, a lay wardly past and inclining downwardly over the fell, and a second arm on the shaft extending in the path of the lay and acting when struck by the lay on the beat-up to retract the finger forwardly of the fell, whereby, after the pick of weft toward the side at which the temple is located'is beaten in and the lay moves back, the finger is projected over the weft and the next pick toward the opposite side loops the weft over and around the finger, which is then withdrawn therefrom on the succeeding beat-up of the lay.

3. A loom comprising a temple, a lay movable toward and from the temple, a selvage loop retaining finger movable substantially parallel with. and above the edge of the cloth adjacent the fell, a rock shaft mounted on the temple, an arm on the shaft connected to the finger to effect the operation thereof, a spring connected to the shaft acting normally to project the finger rearwardly past and inclining downwardly over the fell, a cam plate mounted on the lay and a cam arm on the shaft extending in the path of the cam plate and acting when engaged by the cam plate on the beat-up to retract the finger forwardly of the fell, whereby, after the pick of weft toward the side at which the temple is located is beaten in and the lay moves back, the finger is projected over the weft and the next pick to- 1 ward the opposite side loops the weft over and around the finger, which is then withdrawn therefrom on the succeeding beat-up of the lay.

4. In a loom a substantially straight sel- 1 vage loop retaining fingers having a'downwardly curved rear end and mounted to slide substantially parallel with and above the edge of the fell, and means connected to the forward end of the finger acting normally to project the finger rearwardlypast the fell and to retract the finger forwardly of the fell upon the beat-up of the 'lay, whereby, after the pickof weft toward the side at which the finger is located is beaten in and the lay moves back the finger is projected over the weft and the next pick toward the o posite side loops the weft over and aroun the finger, which is then withdrawn therefrom on the of'the lay.
